This is a change that the USPS is proposing that may affect many mailers. It deals primarily with type-size and spacing requirements for printing of a delivery address on all letter-sized mail pieces.

Here is what the USPS says about the changes:

We are proposing revisions to the address standards for letter-size pieces mailed at automation, presorted, or carrier route rates. Under the new standards, all letters mailed at discount rates must be addressed using a minimum of 8point type. In addition, for automation rate letters, the lines and the characters in the address must not touch or overlap, and each element on the address line may be separated by no more than three blank character spaces.

These changes probably won't effect most mailers, but it is something to be aware of in the future. If you have comments on the changes, they can be submitted before December 10, 2007 to the following address:
